Added

• New math functions: f16.rsqrt, f32.rsqrt, f64.rsqrt.

• New math functions: cospi, sinpi, tanpi, acospi, asinpi,
  atanpi, atan2pi, in each of the f16/f32/f64 modules. (#2243)

• Slight improvements in the ability of the fusion engine to fuse
  across map nests separated by reshape operations. Only works if
  the innermost return type is purely scalar.

• futhark pkg now allows underscores in package paths.

Fixed

• The interpreter no longer crashes when passing a sum-typed value
  into AD, but it is unlikely to produce a usable result (#2238).

• The partial derivatives of comparisons are now always zero.
  Previously we had some code that made an attempt at giving these
  another interpretation, but it was never mathematically sound, not
  useful, and sometimes buggy. (#2239).

• Out-of-bounds reads in GPU backends when transposing a great many
  matrices in parallel (#2241).

• vjp in the interpreter is now asymptotically efficient (#2187,
  #2240). Work by Marcus Jensen.

• The interpreter did not handle open correctly.

• Incorrect handling of some size inference edge cases during
  monomorphisation (#2252).

• Incorrect registration of entry point types when mixing type
  abbreviations and arrays (#2253).

• Reverse mode AD now handles sequential streams. (#2256)
